I worry about this framing, because it suggests that what I (and many other people who I have spoken to) experience, is somehow atypical. I have no objection to talking to people, and I have groups of friends who I like talking to and engage with well. They're going out this evening and I'm not. Why? It's not because I don't like them, or because I don't "gel" with them - it's because it's the end of the week, and social interaction is a tiring event for me. I find it nearly impossible to concentrate on other people or what they are saying, and it only becomes more difficult over time. It's not about practice. To address your comment on D&D, the reason introverted people are more engaged and outspoken during a game is because that is what the game demands. If you were to ask such a person, they would say it is fun, of course, but tiring - and I know that because I am much the same way when I play D&D.
